Division into BLocks. 
In computing the stand and yield the forest was divided into blocks. 
Sections 6, 7, and 8 of T. 24 N., R. 18 E., comprising 1,745 acres of 
the area surveyed, were left out of consideration, because the forest 
upon them has been entirely destroyed. The other 34,236 acres were 
divided into six blocks.

THE LONGLEAF PINE. 
Table I shows the height and clear length of longleaf pine accord- 
ing to diameter breasthigh. It is based upon measurements of trees 
felled by the lumber company in sections 12, 13, and 18 in Block I, 
and upon hypsometer measurements of standing trees on the high ridge 
in sections 21 and 22 in Block VI. Its purpose is to show the differ- 
ence in height between the first-quality timber, which grows on the 
rolling land and has been produced under the most favorable conditions 
of soil and situation, and the poorer quality of timber found growing 
on the tops of the highest hills. - (See Pl. IL.)

Table Il gives the contents in board feet of longleaf pine for sue- 
cessive diameters from 10 to 36 inches. The figures were obtained by 
scaling with the Doyle rule the same trees that were measured for 
Table I. These figures were used to compute the yields of timber 
not only for the Coosa County tract, but also for the Bibb County 
tract. In addition, another volume determination was made for trees 
from 14 to 26 inches in diameter, on the basis of what they actually
